2010 USDA Forest Service, Rocky Mountain Region Aerial Detection Survey Data. This data depicts the occurrence and location of forest insect, disease, and other biotic and abiotic causes of tree mortality and tree damage. Aerial survey data is collected by observing areas of tree damage or tree mortality from an aircraft and manually recording the information onto a map. Due to the nature of aerial surveys, this data will only provide rough estimates of location, intensity and the resulting trend information for agents detectable from the air. Many of the most destructive diseases are not represented in the data because these agents are not detectable from aerial surveys. The data presented should only be used as...

San Diego River Shot Hole Borer Study- Vegetation Data Collected December 2019 through February 2020
Data presented are results of vegetation sampling conducted between December 2019 and February 2020 in 24 survey plots to document the status of infestation by shot hole borers (Euwallacea sp.) on the riparian vegetation at the San Diego River. This dataset presents location, percent cover of different vegetation types, and number of seedlings for each survey plot. In addition, for each tree and sapling in each plot we present species, size, tree status (live, resprouting, recently dead from shot hole borer, or dead from another cause or unknown cause), infestation status (infested by shot hole borer, not infested by shot hole borer, or infestation not confirmed as shot hole borer), and crown condition. For every...

This dataset contains mountain pine beetle infestations from aerial detection survey and GAP landcover data. Categorical values were assigned based on analysis of percentage of evergreen forests affected by mountain pine beetle infestations for the Northwest Plains Ecoregion.

For each damage agent, a composite index was created by analyzing the ADS data for the past 5 years (2005 - 2010)collectively. The assumption is that the longer the infestation has been in one location, the higher themortality. This can then be used to identify those epicenters of high mortality and adjacent areas todetermine the potential for future mortality.

Aerial Insect and Disease Detection Survey(ADS) for Mountain Pine Beetle activity in 1994 - 2010. The ADS data was obtained to be used for BLMs REA Process for the Northwestern Great Plains ecoregion. The original data was combined from USFS regions within the ecoregion then clipped to the Northwestern Great Plains Level III ecoregion plus a buffer that consists of the 5th level Hydrologic Unit Code (HUC) watersheds that intersect the ecoregion.

This dataset contains mountain pine beetle infestations from aerial detection survey and GAP landcover data. Categorical values were assigned based on analysis of percentage of evergreen forests affected by mountain pine beetle infestations for the Middle Rockies Ecoregion. Categorical values were assigned based on key ecological attributes table.
